Ask Albert Einstein is based on a true story about the great scientist with 'kind eyes', who took the time to answer a fifteen-year-old girl's letter asking for help with a math problem. It's narrated by Annabel's little sister, who worries about her big sister's difficulty with math.

Annabel says of her teacher, 'Who does she think I am, Albert Einstein?' So her seven-year-old sister sets out to discover all she can about the scientific genius, and then sends him a letter, asking for help with Annabel's problem. Einstein doesn't give the answer, but his drawing helps Annabel to find the solution herself (the problem and Einstein's hint are included at the back of the book).

It's a lovely story about a little girl's love and concern for her big sister, and a great man's humanity, compassion and kindness. I enjoyed Einstein's quotes (that begin and end the book) as much as the story, quotes like 'Life is like riding a bicycle. To keep your balance you must keep moving.'
